BF3Blog has a screenshot from the Wake Island map in the new Return to Karkand DLC for Battlefield 3, suggesting it's a hint that DICE is gearing up to create Battlefield 2143. This is based on the appearance of the number 2143 on a wall, and they note that Battlefield 2142 was tipped with similar Easter eggs in the Battlefield 2: Euro Forces and Armored Fury map packs. Thanks Computer and Video Games.
